Wow, that's great work, just to check out angles!

Thanks, but then this is the one that worked. As I recall there were three others where the angle was wrong.

As far a tool recursion goes, I used only tools I had made to make a guide to help me make a shell auger correctly.

Some of those tools had been made using tools I had made. One of the chisels I used was made on a homemade forge that was made with several hand made tools. As I shaped the hot plain blade I gripped it with tongs I had made. The shell auger was made in order to make a handles. I made a handle for a bit holder. This bit holder let me remove bits I had made to cut a hexagonal hole in a bronze rod. The hexagonal hole became a collet in a bit holder made from scratch.


Since then that tool has helped me to make other tools that I have used to make tools. The recursion is endless!

As meta as that sounds, I would bet that any serious machinist could come up with much longer lines of recursion than I have. Tool makers use tools and make tools. Chains of causality ensue. The more tools you have and make the deeper intertwined the layers of tool dependency will be.
